We will not solve the obesity problem in America until we stop kowtowing to the food and ag industries and change the USDA Dietary Guidelines, which currently tell us to eat lots of grains, half of which can be refined, and which certainly contribute to obesity. They also advise a low fat diet with lean meat and skim milk, which leaves you hungry and seeking all those fattening grains, and ignores the evidence that kids that drink whole milk are slimmer. Then they recommend 'oils,' including your modern polyunsaturated vegetable oils, which provide too much pro-inflammatory omega-6 fats and are often damaged by the processing which makes them unhealthy. There is little mention of real butter, which provides an excellent source of real vitamin A and contains butyric acid that improves insulin sensitivity. They perpetuate the myth that saturated fat promotes heart disease, when good, unbiased evidence shows that is not true. They perpetuate the myth that fat is fattening because it is concentrated calories, ignoring the evidence that it is really carbohydrates that promote obesity and diabetes, especially if they are refined (3 slices of white bread a day is okay for kids over 14). These are the guidelines that govern school lunches, and apparently guide the processed food industry! Is it any wonder we're raising a generation of fat kids!
